M6 smart motorway J13 and J15: £232m-£335m

The M6 smart motorway project will see major works between junction 13 at Stafford and Junction 15 at Stoke South commence next March.

The works, which form part of the ‘smart spine’ of the motorway network will upgrade 28 km of road, 2 km of new noise barriers, widening of the Creswell Viaduct, new CCTV cameras and upgrades to the Dunston and Norton railway bridges.

All-lane road construction works are expected to start in early 2018.

M25 upgrade J10 to J16: £335m-£479m

With the highest traffic flow anywhere on the motorway network, the upgrades between junction 10 and junction 16 of the M25 will be sorely needed when work starts, expected in March 2020.

With a price tag in the region of £335m to £479m, the upgrade will see all-lane running at J15 to J16 between the M4 and M40 interchanges.

The plans include hard shoulder running between those two junctions, as well as a four-lane through-junction between junctions 10 and 12. There is a separate scheme to upgrade Junction 10.

M54 and M6 junctions 10A and 11 upgrades: £250m-£300m

Scoping work for proposals to add a north-facing access road between the M54 and the M6 and M6 Toll around junctions 10A and 11 of the M6 is in its early stages.

Highways England is weighing up three options at present and will publish a public consultation on the new route.

The project will include new slip roads to be constructed at the M6 junction 10a for Wolverhampton and Telford, which will provide links to and from the M6 to the A460, and would potentially cross the M6 on a new bridge.

M27 smart motorway upgrade: £200m-£250m

The work involves upgrading the M27 to a smart motorway between junction 4 (M3 interchange) and junction 11 (Fareham), linking with the smart motorway scheme on the M3.

The upgrade, which is expected to get under way next year, will provide 48 km of extra capacity on the south-coast road.
